This module is based on the assumption that META.yml is YAML as described by the YAML specification.
This, unfortunately, is not the case. META.yml was created at a time when YAML was immature, and as a result it presents some problems in this regards.
The use of JSON in META.yml is likely to cause problems, and should be avoided wherever possible.
